Which CTU analyst in 24 is played by Mary Lynn Rajskub? The answer is Chloe O'Brian.

Chloe O'Brian is a highly skilled analyst associated with the Counter Terrorist Unit in the television series 24. Mary Lynn Rajskub first joined the show as Chloe at the beginning of its third season in 2003, and the character quickly became one of Jack Bauer's most trusted allies.

Chloe's strengths are computer science, intelligence analysis and rapid problem-solving under pressure. She frequently helps Jack even when doing so violates orders or puts her own career at risk. Her socially awkward manner contrasts with her exceptional technical ability, making her a distinctive presence among the show's field agents and political leaders.

The other options are also 24 characters, which makes the question tricky. Renee Walker is played by Annie Wersching, Michelle Dessler by Reiko Aylesworth, and Nina Myers by Sarah Clarke. Chloe ultimately appeared in 125 episodes of the original series and returned for 24: Live Another Day in 2014.
